摘要： A method for supporting handoff and preventing data loss in mobile communications networks is provided. The method for a mobile node establishing a mobile Internet protocol (MIP) with at least one or more wireless packet service systems, each of which has a serving GPRS support node (SGSN) and a gateway GPRS support node (GGSN), includes: a first SGSN connected to the mobile node transmitting predetermined first connection information on the mobile node to at least one or more second SGSNs adjacent to the first SGSN; the second SGSN receiving the first connection information storing the first connection information as a database item, and transmitting 1 first connection acknowledgement message to the first SGSN; if reception of the connection acknowledgement message is successful, the first GGSN connected to the first SGSN transmitting predetermined second connection information on the mobile node to at least one or more second GGSNs connected to the second SGSN; and the second GGSN receiving the second connection information and then transmitting a second connection acknowledgement message to the second GGSN. By transmitting information on a mobile node required for handoff to adjacent foreign agents (FAs) in advance, when handoff is performed, reliable handoff can be performed quickly without resetting and releasing a PPP, such that IP mobility services can be provided.

摘要： A subscriber input/output device of a high-speed packet switching system with a parallel common bus type is disclosed. The subscriber input/output device uses a coaxial cable to establish a star network of a radius of hundreds of meters, and the star network is arbitrated by a polling method to be used as a near communication network or an internal link network of a large scale communication system. The high-speed performance of 320 Mbps-class with a relatively simple medium access protocol for transmitting data through a common parallel bus is obtained, and broadcasting and multicasting are supported.

摘要： An arbitration switching system and a method of arbitration switching in a high-speed packet switching system uses a subscriber input/output device, an arbitration switching system and a parallel common bus part for the purpose of point-to-point communication point-to-multipoint communication and transferring packets generated in each node. A system bus structure is based on a parallel common bus type. Furthermore, to accommodate high-speed arbitration switching, operations such as polling, arbitration and switching are processed in parallel. Therefore, bus use efficiency is high, and a bus-extension can be easily achieved. A star LAN may be realized because broadcasting and multicasting are supported. An internal high-speed network for interlock in large-scaled communication systems that need high-speed switching can also be provided.

摘要： An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.
